Abstract
A method of routing control information and bearer traffic in a packet network. When a wireless communication device has established a connection in a coverage area serviced by an Access Network Controller (ANC) and a Serving Node and roams into an area serviced by a new ANC and a new Serving Node, the present invention routes control information to and from the device through the anchor Serving Node (Serving Node through which the connection was established). Bearer traffic is routed to and from the device through the ANC and Serving Node serving the area in which the wireless communication device is located.
